Designed to protect your GoPro Hero 5 and 6 camera lens during more extreme outdoor activities. With rock climbing, backpacking, and mountaineering in mind the cap is fabricated from carbon fiber reinforced polymer for maximum durability and light weight (<10g). The cap clips firmly in place on the lens while being transported and when the camera is actively recording. This keeps the cap and camera together and eliminates the need to find somewhere to store the cap while you are filming. A micro-lanyard is included to keep the cap from tumbling off the edge of the crag should you accidentally drop it when removing it. Designed and Manufactured in the U.S.A and backed by Sweeney Engineering’s 100% satisfaction guarantee.
